Application filed December 17, 192$. serial No. delimit To all whom it magi concern."

Be it known that l, DONALD S. BARROWS, a citizen of the United States, residing at Rochester, in the county of Monroe and State, of New York, have invented certain new and useful Improvements in Wear Plates for Car-Truck Side Frames; and I do hereby declare the following to be a full,

be connected to the truck columns for re ceiving the wear incident to the movement of the bolster.

The principal object of the invention resides in the production'of wear pads from I the material salvaged from the blanks used in the construction of wrought metal car --truck side frames, said material being first '25 blanked and then subjected toone or more forging operations wherein the portions of v the plate through which the rivets pass are offset from the body portion of the plate to rovide very" convenient projections in addition to being readily posirecessed to permit of the heads of the rivets being'countersunk beneath the wearing surfaces of the plate.

Another object of the invention is to provide a construction of side frame andbolster wear. ad in which the truck column and stiflenmg flanges borderin the same are embraced by the pad, the o set portions of said ad coasting with the inturned stifiem ing anges in providing a comparatively simple but exceedingly strong construction in which the 0 nings receiving theorivets can be punched: thereby obviating the expense' incident to the employing of special drilling equi ment.- Other advantagea'such as the provid inglof ample space for entering, bucking and driving the rivets follows from my present construction of wearad and vel of the flanges requiring less working and resulting stretching-of the metal, and also improving the appearance of the side frame. With these and other objects in 'view,-the

invention furtherconsists in the construcjplate, and the truck column metal side'frame.

' the stiii'eningh tion, arrangement and combination of the several parts, as well as the method of manufacturing the wear plates, all; as will be more fully hereinafter described.'

In the drawings illustrating the invention, 00 the scope whereof is pointed :out in the claims: 7 Figure 1 is a side view of a fragmentary portion of a car truck side frame showing my improved wear lates applied to the as truck columns thereoil Figure 2 is a view of the wear plate blank cut from the material salvaged from the blank or blanks used in construction of a Wroughtmeta-l car truck, the salvaged mailfllfll being indicated by the dot. and dash mes. l

Figure 3 is a pers tive view of the wear plate blank ass apedby the initial for 'ng or bending operation. T

igure 4 is a face view of the completed Wear plate; a U I a Figure 5 is a horizontal sectional view on the line 55 of Figure 4through the wear showing the same connected to portions of the wrought Referring to the drawings in which similar reference characters desi ate corresponding parts in the several news, the numeral 1 indicates a car truck side frame formed from a sheet metal blank or blanks in which the inner and outer side walls may each be formed with a plurality of top are bar portions, a plurality of bottom arch bar portions and a plurality of truck column portions. The truck column portions-2 are each formed with an inwardly extending flange 3 alon their'outer'edges and an inwardly egzten ing flange 4 along their inner edges, said last named flange forming a beveled portion bordering the upper part of the truck columns and being adapted to have connected thereto the wear plate 5.

I The inturn'ed flanges receiving the wear plates are each disposed so; as to form a bevele'd portion bordering the bolster opening, the angleof'which beveled portion is less than a right angle with'respect tothe adjacent side wall.

flanges ,4 are preferably in- ,turned atrig t angles to the respective side walls, the metal. at the junctionof the bevele'dportions and right angularly disposed portions of the flanges being bent so as to ll!) The lowermost portions of i effect a gradual easement thereof without stretching or otherwise impairing the strength value of the column. As a result of this construction the truck column stiffening flanges bordering the bolster opening can be easily bent in the manufacture of the side frame.

The wear plate 5 is preferably formed from the scrap pieces of the blank or blanks cut from the side walls in the formation of the several side frame portions, said pieces being cut to provide the rectangular blanks 6 from which the wear plate is produced.

The blank 6 is first bent to form the flanges 7 and then subjected to a drop forging operation which, in addition to reshaping said flanges, also forms the projections 8. The projections 8 are pressed from the body web portion of the plate away from the, wearing surface thereof so as to provide recesses 10 into which the heads of the attaching rivets are received, said projections being disposed in ofl'set relation to the wearing surface, but preferabl normally disposed in upright planes. e projections 8 are arranged at an angle to the body web portion corresponding to the angular disposition of the upper portions of the stiffening flanges The metal forming the pro'ections 8 is partly forged from the flanges the recesses receiving the rivets intersecting the bearing areas provided on said flanges adjacentthe wearing surface of the body web.

Each projection '8 is provided with an opening 9 adapted to receive an attaching rivet 11, said rivet being further mserte into a registering openin formed in the adjacent stlflening flange o the truck column.

The rivets are disposed at right angles to the planes of junction of the pro ections and stiffening flanges thereby readily faclh tating the insertion and heading of tl 1e rivet in providing a very strong and r1g1d connection of the wear plate to the truck column.

A bolster wear plate constructed in accordance with thepresent invention provides for an increasedside bearing area and at the same time permits of the use of rivets whlch can be economically applied and properly headed without impairmg the wearing surfaces of the plate.

The method of manufacturing my wear plate consists in cutting a rectangular metal lank to the desired size, then flanging said blank by bending opposite side ed e portions thereof, as shown in Figure 3. e flanged blank is now subjected to one or more forging operations in which the body web portion of the plate and an adjacent flange is shaped to provide an offset projection or attaching portion. I

The metal of the plate is offset at the junction of the wearing surface of the body web and the side bearing'area of the adjacomprising a bod plate adapted to be connected I frame, said plate involving a body web havmg a wearing surface, flanges extending from said body web and providing side bearing areas adjacentthe wearin surface, and

attaching projections extending from the plate, said projections being formed by ofisetting adjacent portions of the body web and flanges. O
